I have a 4G iPod and am using it with an iBook G4. My girlfriend is getting an iPod 5G next week and I want to know if it's possible to have two iPod's registered to the same computer? Are there any known issues? In addition I am not keen to have to manage two iTunes libaries, let alone have them mixed up. She want to convert her CD's onto the iPod but doesn't need to keep the files on my hard disk. I thought maybe if I set her up as a different user on the computer this might keep things seperate. Any suggestions/hints/comments? Thanks.
